hyprctl --batch hyprpaper commands don't work

[timblaktu]

Two hyprpaper commands batched in a single hyprctl command fail:

> hyprctl --batch "hyprpaper wallpaper eDP-1,/home/tim/Pictures/bruno-aguirre-YRfaG3JVwkU-unsplash.jpg ; hyprpaper wallpaper HDMI-A-1,/home/tim/Pictures/spencer-davis-ilQmlVIMN4c-unsplash.jpg"
unknown requestunknown request

While each of the individual hyprctl hyprpaper commands succeed:

> hyprctl "hyprpaper wallpaper eDP-1,/home/tim/Pictures/bruno-aguirre-YRfaG3JVwkU-unsplash.jpg"
ok
> hyprctl "hyprpaper wallpaper HDMI-A-1,/home/tim/Pictures/spencer-davis-ilQmlVIMN4c-unsplash.jpg"
ok

I've tried a lot of syntactical permutations of the batched commands, playing with placement of semicolon and double quotes, to no avail.

Not sure whether this issue is best placed in hyprpaper or hyprland repos but this should be a start of the investigation.

If this is not supposed to work by design, then of course this issue represents either bug against the hyprland/hyprctl docs and/or the hyprpaper docs (should be documented that hyprpaper sub-commands aren't batchable by design) or a feature request (to add support for hyprctl --batch hyprpaper).

My workaround is of course to not batch hyprpaper commands, but this is undesirable for performance reasons as I'm calling these in keybindings when the active workspace changes.

My environment is Arch Linux with:

• 6.5.9-arch2-1 kernel
• hyprland-nvidia-git 0.31.0.r67.g062f7494-1
• hyprpaper 0.4.0-1
• xdg-desktop-portal-hyprland-git 1:r324.3e44c36-1

and
